Sat for the extended version today and cleared it. Don't take it lightly. It's 80 questions in 110 minutes. I did not have enough time left to review the questions. Some questions were especially tricky, some were new to me or I had not come across them before in any of my preparation. Used Linux Academy, Cloud Guru and AWS CSA official study guide. Have confidence in the process and do the hands on. Anthony's labs are good for preparation and his lectures are really good. Read the whitepapers and FAQ's.
